In history essays you need to show that you understand the question you are being asked and that you can illustrate several different interpretations, backing each with evidence. An introduction is needed to start off where you briefly outline the essay. Within the main body of the essay you then need to explain several different points that answer the question, with the one you consider the most significant first if possible. When going through different points it is best to avoid a yes/no answer (e.g. the 1930s were a time of depression because...followed by the 1930s were a time of prosperity because...). If you can integrate the different interpretations into specific points then you will be more likely to get higher marks (e.g. you could talk about high vs low unemployment in different areas, then move on to something else). This will make your essay more interesting to read than a yes/no structure. In the same regard it is good to try and talk about significance to the question within the main body and not just in the conclusion. Every essay needs a conclusion where you make your argument clearly and relate it directly to the question, but it helps to do this very briefly throughout the essay.
